Psychologists at Harvard University have found that pain hurts more when we think that someone intended to cause hurt. Intentional pain also seems to have a fresh sting every time, whereas we get used to unintentional pain.

The next person who reminds you to floss might be your cardiologist instead of your dentist. Scientists have known for some time that a protein associated with inflammation is elevated in people at risk for heart disease. But where’s the inflammation coming from? A new research study shows that infected gums may be one place.

Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth’s most infertile soils into one of the most productive. These early conservationists disappeared 500 years ago, but centuries later, their soil is still rich in organic matter and nutrients. Now, scientists, environmental groups and policymakers forging the [...]

Cancer cells and nervous system neurons may not look or act alike, but both use strikingly similar ways to survive, according to new research.
Researchers may have identified one of the body’s earliest responses to a group of parasites that causes illness in developing nations and are now infecting US soldiers on patrol in Iraq and Afghanistan.

Some echo-locating bats seem to be really quiet, appearing to make echo-locating calls that are no louder than 70 decibels. But no one had successfully recorded their volume under natural conditions, until now. When researchers recorded whispering bats they found that some of them are shrieking 100 times louder than thought.

A “revolution” in the way we illuminate our world is imminent. Innovations in photonics and solid state lighting will lead to trillions of dollars in cost savings, along with a massive reduction in the amount of energy required to light homes and businesses around the globe, researchers forecast.
A study comparing breastfed and formula fed infants across time showed that the known beneficial effects of breastfeeding are greater than the potential risks associated with infant exposure to chemicals such as dioxins that may be present in breastmilk, according to a new report published in Breastfeeding Medicine.
Scientists are developing a mathematical formula to study the rotation of the moon, taking into account its structure, which comprises a solid external layer and a fluid internal core. Their work is part of an international study, which has come up with an improved theoretical model about the orbital and rotational dynamics of the Earth [...]

While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility.
